Improved indexing for distributed virtual university

Many disciplines have been changed through the use of the Internet. Education being among those that suffer the most radical changes. In the project Virtual School of Energoprojekt Group we made a prototype implementation with distributed mobile agents. The role of the mobile agent layer in the entire virtual university framework is to provide support for information retrieval from the Internet. Major enhancements of the proposed architecture of our solution involve traditional indexing which is enriched by inclusion of an extended thesaurus. This extended thesaurus is updated by mobile agents by finding useful content on accessible servers. On the servers not allowing access of mobile agents, standard search engines are used and the results of such standard search are analysed by software agents and added to the thesaurus
